FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 424,589, dated April 1, 1890.-

Application filed May 18,1888- Serial No. 274,341. (No model.)

To aZZ whom it may concern:

Be it known that we, CHARLES ARTHUR, residing at East Orange, and HENRY BAMBER- GER, residing at Newark, in the county of Essex and State of New Jersey, and both citizens of the United States, have invented certain new and useful Improvements in Fan Attachments for Rocking-Chairs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Our improvements relate to mechanisms and devices arranged and combined with a fan and a rocking-chair to cause the movement of the chair to operate the fan automatically;

and the invention consists in the construction and combination of parts hereinafter described, and more particularly pointed out in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of a rockingchair having a fan and our improved mechanism combined therewith for operating the same. Fig. 2 is a plan view of the mechanism as attached to the back of a rocking-chair. Fig. 3 is a detail view of one of the wings of the fan. Fig. 4c is a front elevation of the double friction clutching device with the cover broken away so as to show the arrangement of the binding-plates Fig. 5 is a top view of the'saine, showing only one of the leaves. Fig. 6 is an elevation of the leatherband-adj usting device. Fig. 7 is a central sectional view of the same. Fig. 8 is a plan view of the disk on the sleeve, showing the flat spring coiled thereon; and Fig. 9 is a sectional view showing the fan-driving mechanism.

In said drawings, A. represents a rockingchair withback B and stationary supports 0.

D D are cr0ss-bars on the chair-back, to which the fan attachment is secured.

a is the rod or support for the fan mechan ism, firmly secured to the back of the chair, as at 6/. and a Z) is a bar pivoted to the rod a, as at 0, so as to form a pivoted extension of the rod a and prevent the portion above the back of the chair from being broken if suddenly brought in contact with anything while the chair is being used.

(Z is a rod or bar secured to the top of the bar I) and extending forward over the seat of the chair, as shown in Fig. 1.

e is a supporting-brace for the rod (1.

f is a rod secured to the cross-bar G, extending between the stationary supports 0 C. To this rod are pivoted upright rods 9 g, having their top ends turned in at right angles, or nearly so, so as to be secured rigidly to the clutching deviceh.

i is a flat grooved bandvheel on an adj ustable tightening-pin j.

is another flat grooved band-wheel situated on rod a.

m m is a flat belt connecting said bandwheels i and 7. On the same pin is pivoted a wheel 7t, having its periphery grooved, so as to receive and carry an endless cord or belt n n. This belt or cord 91 n extends around the under side of said wheel k, thence up over grooved pulleys 0 0 on crossbar 0, and thence along and above (1 and around grooved wheel 1), revolving 011 post 7" on end of bar cl, and at a vertical right angle thereto.

S is an annular case covering a fiat spring 2, one end of which is secured to hub or pulley p, as shown in Fig. 9, and theother end to a fiat disk Fig. 9, on which it is coiled, said flat disk being secured to or made integral with a sleeve 1.

u is a fansocket wheel firmly secured to sleeve '1 and provided with sockets u to receive the round end of fans r.

w w are forked levers within the clutching device h, having their forked ends pivoted to cross-bars 7L h in the case or shell of the clutching device and their opposite ends pivoted to circular projections 20 w 011 sliding binding-plates 0c (0, and are kept in position by the spring y, as shown in Figs. 4 and 5.

As the belt m will be liable to stretch from use and get slack, provision is made to tighten it by a thumb-screw 5, working in a project ing shoulder on the bottom of the frame a, as seen in Fig. 1. By means of this thumb-screw the pivot j, on which wheelt' revolves, is raised or lowered in the groove as, (seen in Fig. 7,) and in this manner the flatbelt passing over wheel i is tightened or loosened, as may be desired.

The levers w w are so arranged in the clutching device that they shall hold the bindingplates as w against the belt in such manner that the belt can only be carried in the direction'shown by the arrows in Fig. 4.

The fans 1) are of the ordinary rotary-fan construction and can be so arranged in the socket-Wheel as to throw the circulation of the air downward or upward, as may be desired. These fans revolve in a plane parallel, or nearly so, with the plane of the chair-seat.

In the drawings the form of rocking-chair shown is that in which the rocking section rests and moves upon another section, being held by front and rear springs, as seen in Fig. 1. These springs keep the rocking sections in position and serve to keep the chair in position shown in Fig. 1 when not in use.

In operation when the occupant in the chair rocks backward the clutching device is forced upward, binding and holding firmly the leather band upon one side only and carrying it along with it, thus causing the wheel to revolve on its axis, and by means of the cord imparting a rotary motion at once to the sleeve and fan-wheel thereon. When the backward motion of the rocker has ceased and the forward movement begins,

the clutching device releases its hold and seizes upon the other side of the band and carries it downward, thus continuing the rotary motion of the fan in the same direction. In this manner the fan is kept continually in motion in the same direction as long as the rocking continues. To provide against the sudden shock and jar in starting and stopping the fans, we have arranged the coiled spring on the disk, as before referred to, the operation of which is as follows: hen the chair is at rest, the spring is entirely unwound in the disk. As soon as the chair is started in either direction the first action is to wind up the spring as the sleeve commences to revolve, thus giving the fans an easy motion in the beginning. As soon as the spring is wound up in the disk it remains so until the rocking of the chair has ceased, when the fans will continue to revolve until the spring has entirely unwound, and at the same time gives a steady motion to the fans.

Having thus described the invention, what We claim as new is- 1. The within-described automatic fan attachment for rocking-chairs, consisting of an upright rod secured to the back of a rocklngchair, having a pivoted extension andearrying a horizontal arm, an adjustable pin carryin g a grooved band-wheel on the lower end of the rod, a grooved band-wheel revolv ng on a pin rigidly secured to said rod at a polnt near the vertical center of the back of the chair, a belt or band connecting said bandwheels, upright rods pivoted at their lower ends to the stationary section of the chair and at their upper ends to a clutching device arranged, as described, to alternately seize and disengage one side or the other of the bands as the rocker is moved, a grooved pulley on the upper pin, a revolving post or sleeve on the end of the horizontal arm, a grooved pulley on said sleeve, an endless cord connecting said pulley on the sleeve with the pulley on the upright rod, a fan-socket wheel secured to said sleeve, fans secured to saidsocketwheel, and a coiled spring secured in a drum and connected with said pulley-wheel, all said parts being arranged and combined as shown, and for the purposes set forth.

2. In a fan attachment, the combination of the upright rods pivoted to the baseof a rocking-chair, the clutching device carr ed thereby, the flat belt operated on by said clutching device, the grooved wheels driven by said belt mounted on the moving portion of the rocker, the endless cord, the fan-socket wheel operated by said cord, and the drum having the coiled spring therein, substantially as described.

3. In an automatic fan attachment for rocking-chairs, a driving mechanism consisting of a grooved band-wheel 7c, band m, grooved band-wheel Q1, clutching device it, and rods g g, secured at one end to the clutching device and at the other end pivotally connected wlth the stationary section of the 'chair, substantially as and for the purposes set forth.

In testimony that We claim the foregoing we have hereunto set our hands this 28th day of April, 1888.
